How to fix: Err:4 http://dl.google.com/linux/chrome/deb stable InRelease in ubuntu 20.04 LTS
Solution 1:
Try this.
Open the 'Software & Updates' program. Under Other Software look for the repository. It should be called something like 'Google Chrome Stable.'
Click on that repository and click remove. Then, just reinstall Google Chrome and the repository should be reinstalled with the correct configuration.
EDIT: You can do this by typing the following commands:
$ wget https://dl.google.com/linux/direct/google-chrome-stable_current_amd64.deb
# sudo dpkg -i google-chrome-stable_current_amd64.deb
